REQUEST A DIAGNOSIS
Tell Us About Your Package Unit Problem
Describe what's happening with your system—strange noises, weak airflow, not cooling or heating—and we'll review the details so our technicians arrive ready to diagnose. The more detail you can give us, the better we can prepare.
WARNING SIGNS
Signs Your Package Unit Needs Repair
System Not Cooling or Heating at All
Your package unit runs, but no conditioned air comes out of the vents. This points to refrigerant loss, a failed compressor, or a blower motor issue. A complete loss of heating or cooling demands fast attention—your home temperature will drift, and further damage can occur if the system keeps running.
Weak Airflow or Strange Noises
Weak airflow suggests a clogged filter, blocked condenser coils, or a failing blower motor. Strange noises—grinding, squealing, hissing—often indicate bearing wear, refrigerant leaks, or an electrical problem. Both require diagnosis before the system fails entirely.
Unit Leaking Refrigerant or Water
A visible refrigerant leak appears as oily residue around the unit or tubing. Water pooling under or around the package unit points to a blocked condensate drain or evaporator coil damage. Refrigerant leaks reduce efficiency and can shut the compressor down; water leaks can damage the mounting area.
Higher Than Usual Energy Bills
A sudden jump in heating or cooling costs often means your package unit is losing efficiency—struggling harder to maintain your set temperature. Refrigerant loss, airflow blockage, or electrical inefficiency all drive up runtime and energy use.
Unit Trips Off or Cycles Frequently
Package units that shut off after a few minutes and restart repeatedly (short-cycling) are working too hard. This pattern typically signals a refrigerant charge issue, high discharge pressure, or a malfunctioning thermostat. Constant cycling wears components fast.
Visible Rust or Corrosion on the Outdoor Cabinet
Rust spots or corrosion on the metal cabinet indicate moisture intrusion or salt exposure. Corrosion can eat through housing, weaken mounting, and expose internal components to weather. Early repair prevents cabinet failure and internal rust damage.
OUR REPAIR PROCESS
How We Repair Your Package Unit
We start with a complete system inspection—refrigerant charge, electrical connections, airflow, and compressor operation. Our technicians run diagnostic tests to identify the root cause, not just treat symptoms. You'll understand exactly what's wrong before we discuss repair options. Package units are unique because they house both indoor and outdoor components in one cabinet, so we inspect internal airflow paths, the condensate drain system, and all electrical connections for corrosion or loose terminals.
- Full refrigerant pressure and temperature checks
- Electrical system testing and continuity checks
- Compressor current draw and operation verification
- Condenser coil cleaning and airflow assessment
- Blower motor performance and bearing inspection
- Condensate drain system and pan inspection
- Internal corrosion and component wear evaluation
Once we've identified the problem, we explain your choices. Some repairs extend unit life; others may lead toward replacement. We'll give you a flat-rate or hourly estimate before we start work, so there are no surprises. If a repair doesn't make financial sense, we'll tell you upfront rather than charge you for work that won't solve your problem. We're committed to your long-term home comfort, not just today's service call.
- Detailed written estimate for all repair work
- Explanation of why each repair is necessary
- Discussion of long-term replacement value if relevant
- Options for financing major repairs through our partners
- Cost-benefit analysis of repair versus replacement for your unit's age
Our technicians handle each repair carefully—refrigerant recovery, component replacement, sealant application, and pressure testing. We use quality replacement parts and Armstrong/Ducane originals whenever possible. Every repair is tested before we leave your home. We follow EPA and manufacturer guidelines for refrigerant handling, ensuring your system stays charged correctly and safely. Work is performed inside your mechanical room or equipment area with minimal disruption to your daily routine.
- Proper refrigerant recovery and evacuation (EPA-compliant)
- Component replacement with tested, quality parts
- Pressure testing and system balance
- Performance verification under heating and cooling load
- Cleanup and equipment protection during work
After repair, we run the unit through both heating and cooling cycles to confirm it's working correctly. We'll check refrigerant charge, airflow, and energy efficiency. You'll know the job is complete and your system is reliable again.
- Full operational testing in both modes
- Thermostat cycling verification
- Proper refrigerant charge confirmation
- Energy efficiency baseline check
You'll receive warranty documentation covering the parts we replaced and the work we performed. Our team can also recommend maintenance to prevent future problems. If you're interested in a maintenance plan, we'll provide enrollment details so you avoid another costly repair.
- Comprehensive repair warranty details
- Maintenance plan recommendations
- Next-visit scheduling to keep your system running

REPAIR SOLUTIONS
Common Package Unit Repairs We Handle
Compressor Replacement
The compressor is the heart of your package unit. When it fails—usually signaled by a complete loss of cooling or heating—replacement is often the best option. We can help you decide between full system replacement or compressor-only repair, depending on your system's age and efficiency. Discuss Your Compressor Options
Refrigerant Charge & Leak Repair
Low refrigerant reduces cooling or heating output and forces the compressor to work harder. We locate the leak, repair it, evacuate the system properly, and recharge to the correct level. This is one of the most common and cost-effective repairs. Schedule Your Repair
Condenser Coil Cleaning & Repair
Dirty or damaged condenser coils reduce heat rejection and force your unit to cycle longer. We clean coils, check for leaks, and repair damage. Seasonal cleaning prevents many condenser problems and restores efficiency. Schedule Preventive Maintenance
Blower Motor & Fan Blade Service
A faulty blower motor means weak airflow or no airflow. Worn bearings squeal; broken blades rattle. We replace or repair the motor assembly, test the blades, and verify airflow performance before we leave. Request Repair Service
Thermostat Troubleshooting & Replacement
If your package unit isn't responding to temperature adjustments, the thermostat may be miscalibrated or failed. We test and replace thermostats, ensuring your system responds correctly to your settings. Contact Our Team
Electrical Component Repair & Replacement
Package units have contactors, capacitors, relays, and disconnect switches. When these fail, the unit may not start or may cycle erratically. We test and replace electrical components to restore reliable operation. Schedule Electrical Repair
Condensate Drain Cleaning & Repair
A clogged condensate drain causes water to back up into your unit or onto your roof. We clean drain lines, repair damage, and check the condensate pump if present. Proper drainage prevents water damage. Request Drain Service
Cabinet Rust Repair & Weatherproofing
Surface rust can spread if not addressed. We clean rusted areas, apply protective coating, and seal any gaps. Weatherproofing extends cabinet life and prevents moisture intrusion. Get Your System Protected
FAQ
Frequently Asked Questions About Package Unit Repair
A: We help you make that decision based on your system's age, repair history, and overall efficiency rather than guesswork. If your unit has needed multiple repairs recently or its efficiency has dropped significantly compared to newer equipment, replacement may be the more cost-effective option long-term. Our diagnostic gives you the facts you need to decide with confidence.
A: We specialize in Armstrong Air and Ducane as our primary dealers, so we stock common parts and know these systems thoroughly. We can diagnose and repair most other residential package units as well, though original parts for less common brands may take longer to source. Call us with your brand and symptoms, and we'll let you know exactly what we can do.
A: Repair costs vary widely depending on what's actually wrong — a refrigerant recharge is priced very differently than a compressor replacement, for example. We give you a flat-rate estimate before we start any work, so you know the investment upfront with no surprises later. Financing is available through our partners to spread costs across manageable monthly payments.
A: Simple repairs like a refrigerant recharge or coil cleaning are often completed in a single visit of an hour or two. More involved repairs, such as compressor or motor replacement, can take longer depending on the unit's design and parts availability. We'll give you a realistic time estimate during the diagnostic so you can plan your day accordingly.
A: Some cycling is completely normal — the unit runs until it reaches your set temperature, then shuts off until it's needed again. If it's cycling every few minutes instead (short-cycling), that's a sign of a problem. Short-cycling usually indicates low refrigerant, high pressure, a failing thermostat, or an undersized unit. Bring it to our attention so we can properly diagnose the cause.
A: Turn off the unit to stop the leak from getting worse, and give us a call to describe what you're seeing. Don't let it keep running—continued operation can damage the compressor further. We'll find and repair the leak, then evacuate and recharge the system safely. Refrigerant recovery is required by law, and we handle it properly every time.
A: Absolutely. Regular maintenance catches small problems before they become big, expensive ones down the road. We clean coils, check refrigerant charge, test electrical components, and replace filters at every visit. Most maintenance-plan members report meaningfully lower repair costs and longer system life compared to homeowners who skip routine service entirely.
A: Yes. We work with Wisetack to offer flexible payment plans for repairs of any size. If the repair cost is significant, financing spreads payments out over several months, making it easier to manage within your household budget. Ask us about current options and terms during your repair estimate.
A: Our warranty covers the parts we replaced and the work we performed during the repair visit. If something doesn't work as expected afterward, let us know and we'll return to diagnose and fix it at no additional charge for our labor. We stand behind every repair we complete, and our warranty documentation outlines exactly what's covered.
A: We recommend twice-yearly maintenance—a spring tune-up before cooling season and a fall tune-up before heating season—to catch wear on both sides of the system. Maintenance plan members get automatic scheduling reminders and member discounts on any service work. Even without a plan, annual service at minimum keeps your system running efficiently and helps preserve your manufacturer warranty.
